Winterization
Its that time of year when the IFR pilots primary aviation weather concern finally shifts completely from thunderstorms to airframe icing. Even if weve been forced to consider both hazards on the same flight, we probably can leave the thunderbumpers by the wayside for a few months. In truth, we should always be concerned about airframe icing, depending on the altitudes at which were flying. But winters onset doesnt mean airframe icing is the only operational concern we might face. In last months issue, Mike Gugeler tackled the topic of runways contaminated by rain, snow, slush, ice or a some evil combination. This month he serves up a detailed discussion on preheating. As Mike demonstrates, thinking about the whole airplanes preheating needs is not just a good idea, its also a significant safety consideration.
